Zoro Select 11L863 PTFE Syringe Filter

This sterile syringe filter features a 30 mm PTFE membrane with a 0.22 um pore size for aqueous and solvent filtration. It is supplied in a pack of 30 units suitable for laboratory sample preparation. The housing accepts a maximum capacity of 100 mL and operates up to 65 psi. The filter connects via a female Luer lock inlet and a male Luer slip outlet.

Installation and Common Issues

The filter twists onto a compatible female Luer lock syringe and the outlet slips into a male Luer fitting for a secure flow path. Sterile packaging allows immediate use without additional cleaning steps. Over-tightening the connections can damage the housing or compromise the seal. Exceeding the 4.5 bar pressure limit may rupture the membrane and cause sample loss.

Suitable Users and Limitations

This product suits labs requiring sterile PTFE filtration for HPLC sample prep or general clarification in 30 mm format. Buyers needing non-sterile filters or larger membrane diameters for higher throughput should look elsewhere. The 100 mL maximum capacity limits use with larger volume syringes. Users requiring different pore sizes for specific particle retention must select an alternative filter.

Questions about this item

How can I confirm the PTFE syringe filter is functioning correctly after installation?

Verify that liquid passes through the 30 mm membrane at up to 65 psi without leakage at the female Luer lock inlet or male Luer slip outlet, and that the 0.22 um pore size provides the expected sterile filtration for volumes up to 100 mL.

What comes in the package and what additional items are required?

The pack contains 30 sterile PTFE syringe filters with 30 mm housing diameter, female Luer lock inlet and male Luer slip outlet; syringes compatible with female Luer lock connections must be purchased separately.

Which pore size and diameter version should I select for sterile filtration of 100 mL samples?

Choose the 0.22 um pore size with 30 mm membrane diameter, rated for 65 psi maximum pressure and 100 mL capacity, supplied sterile in a pack of 30.
